fix(inventory, orders, pos): удалена зависимость от django-simple-history для tenant-моделей

- Добавлен pre_save сигнал для Order вместо django-simple-history
- Переписаны все функции signals.py без использования instance.history
- Заменены .username на .name|default:.email для CustomUser в шаблонах
- Исправлен CSRF-токен в POS для работы с CSRF_USE_SESSIONS=True

Теперь создание заказов работает корректно в мультитенантной архитектуре.
